New species, identification keys and notes on Lamiinae (Coleoptera, Cerambycidae) from the Neotropical regionAuthorNascimento, Francisco E. De L.textZootaxa20182018-08-0844572315324journal articlehttps://doi.org/10.11646/zootaxa.4457.2.71175-53261457790E8A85C81-6A57-4906-8664-E8BE78C9A872Drycothaea
Thomson, 1868
Drycothaea
is currently composed of 27 species distributed in the Neotropical region (
Monné 2018
;
Tavakilian & Chevillotte 2017
). When studying the South American species,
Martins & Galileo (1990)
characterized
Drycothaea
as follow (translated): “Mesoventrite with tubercle; prothorax with lateral spine; scape without cicatrix at apex; pronotum without evident tubercles; elytra convex, without longitudinal carina and not depressed near suture.”
In April the following year
Galileo & Martins (1991)
, proposed some transferences and synonymies, adding
D. mexicana
(
Breuning, 1974
)
(originally
Thrychestola
mexicana
) to this genus. Although the synonymy was formally made by
Galileo & Martins (1991)
, it was done so based on personal communication with Dr. Gérard L. Tavakilian
MNHN
(Muséum National d’Histoire Naturelle) who listed the same name as a new combination on August of the same year (
Tavakilian, 1991
). Later,
Galileo & Martins (2010)
included
D. mexicana
in a key to the species of the continental America (which excludes the Antillian species) at alternative of couplet “10” (translated): “Pubescence of head, pronotum, and basal area of elytra yellowish, remarkably contrasting with darkbrown remaining pubescence of elytra.” The photography of the
holotype
of
T.
mexicana
(
Figs 14-16
), revealed that
Galileo & Martins (1991
,
2010
) erroneously identified a specimen (a new species described herein) deposited at
MZSP
as being
D. mexicana
.
Besides other differences,
D. mexicana
has uniform yellowish pubescence on the head, pronotum and base of the elytra.
Through the study of the tarsal claws of the holotype, it was also possible to confirm that
D. mexicana
is truly a
Calliini
and belongs to
Drycothaea
.
Below, we are describing the specimen erroneously referred to as
D. mexicana
by
Martins & Galileo (1991
,
2010
).
